Struct naga::valid::analyzer::ExpressionInfo

pub struct ExpressionInfo {
    pub uniformity: Uniformity,
    pub ref_count: usize,
    assignable_global: Option<Handle<GlobalVariable>>,
    pub ty: TypeResolution,
}

Information about an expression in a function body.

Fields

uniformity: Uniformity

Whether this expression is uniform, and why.

If this expression’s value is not uniform, this is the handle of the expression from which this one’s non-uniformity originates. Otherwise, this is None.

ref_count: usize

The number of statements and other expressions using this expression’s value.

assignable_global: Option<Handle<GlobalVariable>>

The global variable into which this expression produces a pointer.

This is None unless this expression is either a GlobalVariable, or an Access or AccessIndex that ultimately refers to some part of a global.

Load expressions applied to pointer-typed arguments could refer to globals, but we leave this as None for them.

ty: TypeResolution

The type of this expression.
